PTSD

[markusaurelius]

I would think it was quite likely. I bet the few soldiers that survived the Varus disaster weren't too normal after that ordeal. I think any fighting unit that has trained, campaigned and lived together for 25 years would be affected when their life long friends got hacked to pieces, killed by the plague, hit by an arrow, captured and tortured....... this list goes on.

I would guess though that it wasn't as common as in modern times for all the reasons mentioned above.
